MATERIAL-HANDLING APPARATUS.

Application flied December 29, 1924. Serial no. 758,787.

This invention relates to material handling apparatus, and moreparticularly to mechanism for controlling the speed thereof.

The primary object of the invention is to provide, in a materialhandling apparatus,

an improved mechanism whereby the operating speed is directly controlledby the character of the material being handled.

Other objects and advantages will become apparent in the followingdetail description, and the novel features of the invention will beparticularly pointed out in the appended claims.

In accordance with the general features of the invention as hereindisclosed, the air wiping die of a cable painting machine such asdisclosed in the patent. of Frederic S. Kochendorfer and Helmer J. Boe,No. 1,526,071, issued February 10, 1925, is provided with an elongatedshank or stud whose length varies for various sizes and type of cables.When the-die is mounted in its operative position, the end of the shankengages one end of a pivoted member which carries, at its opposite end,aplurality of electrical contact members adapted to establish either of aplurality of electrical circuits which control the speed of the driving.

Referring now to the drawings in detail wherein like referencecharacters designate like parts throughout the several views, 15indicates the base or supporting member of a cable painting machine suchas disclosed in the above mentioned patent. Positioned at one end of thebase member 15 is an electric drivin motor 16 which is controlled by anoperating switch 14 positioned within convenient reach of the operator.Supported at the opposite end of the base member 15 is a' paintcontainer 17. Directly connected to the motor 16 is a main driving shaft18 to WhlCh 1s secured a bevel pinion 33 which meshes with a bevel ear34 secured to a vertically disposed sha t 35 (Fig. 1).

Secured at the lower end of the shaft 35 1s a bevel p nion 36 whichmeshes with a bevel gear 37 secured to a horizontal shaft 38. A gear 40is keyed to the shaft 38 and meshes w1th gears 41 and 42 positioned ateither slde thereof and secured to shafts or reel spindles 43 and 44,respectively. Reels 72, 72, are suitably mounted on the spindles 43 and44 and may be used interchangeably as supply or take-up reels throughmechamim disclosed in the above mentioned pat en A plurality of groovedpulleys 115, 115 rotatably supported in suitable bearings serve to guldethe cable in its travel from the supply reel 72 into the paint container17, whereln it receives a coating of paint, and then to the take-up reel72. After passing around the guide pulleys 115 mounted at the bottom ofthe paint container 17 the cable passes through an air wiping die 12()positioned near the top of the container, which serves to remove thesurplus paint from the cable before being wound on the takeup reel. Theair wiper 120 is connected to a compressed air line 122 which iscontrolled by a valve 123. Secured to the container 17 1s a bracket orsupport 124 provided with a 90 depression 125 for the reception of thewiper 120 (Fig. 2).

The air wiping die 120 is fully described in the above mentioned patent,and accordmgly, a detailed description herein of the die, aside from theportion thereof which forms the subject-matterof the presentapplication, in thought unnecessary.

The air line 122 is connected with a passage 134 in the bracket 124,which in turn 100 is connected with a passage 138 in the air wiplng die120. Formed in the die 120 at right angles to the passage 138 andconnecting therewith are passages 141 and 142 (Fig.

4). A vertical passa e- 145 is provided 105 throu h the center of thedie 120, and midway etween the passages 141 and 142, to permit thepassage of the cable therethrou h. In the drawing, a flat typeswitchboard ca lo 109 has been h wn and. the passage 145 has across-section similar to that of the cable,

a suitable space is allowed between the surface of the cable and thewall of the passage 145 to permit the removed surplus pamt to flow freelback into the container 17 1f a cable which is circular in cross-section1s to be operated upon, the passage 145 Wlll. be circular to correspond.Connecting the passage 145 with the passages 141 and 142 are a pluralityof comparatively fine passages 146 which are formed at such an angle tothe passage 145 that all are directed at the pass ing cable.

Suitably attached to the w1p1ng die 120 is a stud or shank 132 whichpasses through an aperture 147 in the bracket 124 and through an opening148 in the side of the container 17. The die 120 and its shank 132 aresecurely held in place by a set screw 160 which is threaded through thebracket 124 and is adapted to engage an aperture 161 formed in the shank132. The end of the shank 132 protruding from the side of the container17 engages one end 163 of a pivoted member 164 which is pivotedintermediate its ends at 165, and is inclosed within a housing 166suitably secured to the container 17. The other end of the member 1641sbifurcated and terminates in two legs 187 and 188. Electrical contactmembers 167, 168, and 169 are carried by the leg 187 and an electricalcontact member 189 is carried by the leg 188 (Fig. 3). Mountedwithin-the housing 166 and positioned to be engaged by either thecontact member 189 or the contact members 167, 168, and 169 are threecontacts 170, 171, and 172 which are connected with the low speedterminals 180, 181, and 182 of the motor 16 (Fig. 5). Contacts 173, 174,and 175 which are connected with the high speed terminals 183, 184, and185 of the motor 16 are also mounted within the housing 166 and arepositioned to be engaged by the contact members 167, 168, and 169 whenthe member 164 is moved to a predetermined position. Positionedintermediate the low speed contacts 170, 171, and 17 2 and the highspeed contacts 173, 174, and 175 are three electrical contacts 176, 177,and 178 whlch are connected with any suitable source of power, such as agenerator 190 indicated conventionally in Fig. 5.

When it is desired to operate the driving motor at a low speed, theshank 132 01 the air wiping die 120 is of such a length that whenmounted in its operative position, the member 164 is displaced on itspivot 165 so that the contact members 167, 168, and 169 bridge the lowspeed contacts 170, 171, and 17 2 with the line contacts 17 6, 177, and178, respectively (Fig. 3). A tension spring 179, mounted within thehousing 166 serves to urge the end 163 of the member 164 against the endof the die shank 132. In order to run the driving motor at high speed,which is desirable for certain types and sizes of cable, the air wipingdie is provided with a slightly shorter shank thereby allowing themember 164 to assume the dotted position shown in Fig. 3, wherein thelow speed contacts 170, 171, and 172 are bridged by the contact member189 and the high speed contacts 173, 174, and 175 are bridged with theline contacts 176, 177, and 17.8, respectively, by the contact members167, 168, and 169.

In operating the above described apparatus, after the proper air wipingdie has been mounted in position, it is only neces- \sary for theoperator to use the switch 14, the proper driving speed beingautomatically selected by means of the length of the die shank 132.
